The Water Crisis IELTS Reading: Practice Questions and Answers

This passage tests your skills mainly through Matching Headings and Summary Completion questions, covering Questions 1-7 and 8-13, respectively. These formats require you to quickly spot key ideas in each paragraph and accurately fill in missing details, reflecting two essential abilities IELTS examiners look for.

Here are some sample paragraphs showing how these questions connect to the text and how to approach them effectively:

Paragraph 1:

Per capita water use has increased steadily for decades. As nations become more industrialised and incomes rise, individual water consumption also grows. In the U.S., annual per capita water withdrawals reach around 1,700 cubic metres, four times that of China and fifty times Ethiopia’s level. Today, the limited global supply of renewable fresh water must support both a larger population and higher usage per person. Long-term solutions depend largely on proper pricing models and consistent conservation efforts.

Paragraph 2:

Roughly 70% of all fresh water is used in agriculture, making irrigation a key area for improvement. Current irrigation efficiency is estimated at only 50%. Basic upgrades can raise that number, but many developing countries lack the investment and training to implement such changes. After farming, industry ranks second in water use. It generates much more economic output per litre—around sixty times more than agriculture. Still, some industrial processes are highly water-dependent. Producing 1 kg of aluminium can require up to 1,500 litres of water. Paper manufacturing also uses significant amounts. While newer technologies have lowered consumption, large-scale savings are still possible.

Paragraph 3:

In wealthier countries, water use has been controlled through pricing and improved recycling. Since 1950, U.S. industrial output has quadrupled while water use has dropped by over 30%. Germany and Japan have followed a similar path; Japanese industries now recycle over 75% of the water they use. In contrast, industrial water demand continues to rise in developing nations. With household and agricultural needs also expanding, existing water systems are under increased pressure.

Paragraph 4:

Many analysts argue that pricing water based on its actual supply cost is the most effective way to reduce overuse. This would encourage individuals and industries to adopt water-saving technologies and recycling systems. Most governments still offer water, particularly for agriculture, at prices far below the real cost. In California, for example, farmers pay less than 10% of the actual supply cost. In many lower-income countries, irrigation water is almost free, and energy subsidies allow farmers to pump water continuously. Water, once treated as a public resource, is increasingly seen as a traded commodity. The 1970s oil crisis showed how price hikes and supply concerns led to major advances in energy efficiency. A similar focus on efficient water use is likely the most practical and cost-effective approach to balancing supply and demand.

Paragraph 5:

Reducing water loss through leakage is one of the simplest ways to cut consumption. In several major cities across developing countries, more than 50% of water entering the system is lost due to damaged pipes, faulty taps, and poor infrastructure. Even in the UK, around 25% of water was lost in the early 1990s because of outdated systems. A large amount of water is also wasted when used water from drains, sewers, and industrial sites is discarded into rivers or the ocean. A more current approach treats this water as a usable resource. After appropriate treatment, it can be reused for farming or even reintroduced into domestic supply systems. Israel has invested heavily in this method, soon, recycled water will serve as the main source for agricultural irrigation. In St. Petersburg, Florida, all municipal water is treated and reused in homes.

Paragraph 6:

Conserving water can also be supported by responsible environmental management. Human actions that disrupt natural ecosystems often reduce rainfall and increase surface runoff. For example, deforestation linked to India’s Kabini dam project led to a 25% drop in local rainfall. This pattern has been reported in various places affected by extensive forest clearance. Plants, grass, and other natural cover help absorb rainfall and hold it in the soil. When vegetation is removed, water flows quickly over the surface, leading to erosion and lost groundwater recharge instead of soaking into the earth.

Paragraph 7:

Global warming is expected to change rainfall patterns, though exact outcomes are still debated. As sea levels rise, low-lying coastal nations may face increased saltwater intrusion into freshwater sources. Shifts in rainfall could significantly affect crop production, positively or negatively, depending on the region. Broad projections suggest rain belts may move northward, worsening water shortages across Africa, the Middle East, and the Mediterranean.

Let’s begin with the first type of question you’ll face. Matching Headings tests how well you grasp the main idea of each paragraph. Here’s how to break it down.

Matching Headings in The Water Crisis: Q1-7 Breakdown

In “The Water Crisis” passage, the first seven questions ask you to match headings to paragraphs that often discuss overlapping issues like water consumption and environmental impact. Because the water crisis reading answers share similar vocabulary and themes, it’s easy to confuse their main points.

Below is a list of headings representing the main ideas of the passage. For each paragraph, choose the heading that best summarizes its content.

List of Headings

i. American water withdrawal

ii. Economic pricing

iii. What the future holds

iv. Successful measures taken by some

v. The role of research

vi. The thirsty sectors

vii. Ways of reducing waste

viii. Interdependence of natural resources

ix. The demands of development

x. The consequences for agriculture

Review the list carefully, then read each paragraph to identify the main idea before selecting the best match.

Q1: Paragraph A

Focus: Checking how population and development affect water demand

Strategy: Identify if the paragraph discusses growth in population and usage patterns

Impact: Tests your ability to link large-scale development with increasing water pressure

Answer: ix. The demands of development Explanation: Paragraph A highlights how rising population and higher per-person consumption stress the available freshwater supply. It also shows that industrialization and wealthier lifestyles drive this increase. This directly relates to the growing demands caused by development, making heading ix the best fit.

Q2: Paragraph B

Focus: Identifying major users of water resources

Strategy: Look for sectors (like agriculture or industry) that dominate water usage

Impact: Assesses your understanding of water distribution across different economic activities

Answer: vi. The thirsty sectors Explanation: This paragraph clearly names the two most water-intensive sectors: agriculture and industry. Agriculture alone uses about 70% of all fresh water, making it the largest consumer by far. Then it points out how inefficient irrigation is and how developing nations struggle to upgrade their systems. After that, it shifts to industry, giving examples like aluminium and paper manufacturing. These details prove the paragraph’s goal is to highlight which sectors consume the most water, fitting heading vi.

Q3: Paragraph C

Focus: Recognizing countries that have taken successful water-saving actions

Strategy: Look for nations mentioned alongside positive changes in water use

Impact: Tests your ability to spot case studies of effective resource management

Answer: iv. Successful measures taken by some Explanation: Paragraph C gives clear examples of how developed nations have improved their water management. The U.S. has cut water use by over 30% despite a massive rise in industrial output. Japan now recycles 75% of its industrial water. Germany has also implemented similar practices. These actions are all presented as successful steps. The contrast with rising demand in developing countries only strengthens the focus on effective solutions. That makes heading iv the best match.

Q4: Paragraph D

Focus: Understanding how pricing can reduce overuse of water

Strategy: Look for discussion around cost, pricing policies, and subsidies

Impact: Evaluates your grasp of economic tools used to manage natural resources

Answer: ii. Economic pricing Explanation: This paragraph focuses entirely on the argument that water should be priced according to its actual supply cost. It suggests that fair pricing would encourage both individuals and industries to conserve water and invest in recycling technologies. The text explains that most governments heavily subsidise water, especially for agriculture, leading to misuse. The example of California, where farmers pay less than 10% of the true cost, supports this. The emphasis on pricing as a tool to reduce overuse aligns directly with heading ii.

Q5: Paragraph E

Focus: Finding solutions for reducing unnecessary water loss

Strategy: Identify practical methods like leak reduction or recycling

Impact: Tests your ability to pick up on problem-solving ideas

Answer: vii. Ways of reducing waste Explanation: This paragraph presents practical, low-tech solutions to water waste. It begins with the problem of leaking infrastructure, which causes massive water loss, even over 50% in some cities. Then it moves to how wastewater from homes and industries is often discarded instead of reused. Several countries are named, including Israel and the U.S., that treat and recycle this water. These steps are all aimed at cutting down unnecessary waste, making heading vii the most appropriate choice.

Q6: Paragraph F

Focus: Understanding the link between ecosystems and water availability

Strategy: Spot how natural systems like forests affect the water cycle

Impact: Measures your ability to identify environmental interdependence

Answer: viii. Interdependence of natural resources Explanation: The paragraph discusses how environmental damage disrupts water systems. Deforestation reduces local rainfall and increases runoff, making it harder for water to soak into the ground. The example of the Kabini dam in India shows a 25% drop in rainfall after tree removal. The paragraph makes it clear that natural elements like vegetation are essential for water retention and soil health. It shows how ecosystems and water supplies are interconnected, so heading viii fits best.

Q7: Paragraph G

Focus: Identifying predictions about how water supply might change

Strategy: Look for future-oriented language and uncertainty

Impact: Assesses your comprehension of projected environmental shifts

Answer: iii. What the future holds Explanation: Paragraph G talks about the future impact of global warming on rainfall and freshwater availability. It discusses how rising sea levels may allow saltwater to invade groundwater supplies, especially in coastal regions. There’s also mention of rain belts shifting, which could worsen water shortages in already dry regions like Africa and the Middle East. These are clear forecasts and predictions, indicating a forward-looking paragraph. This makes heading iii the most suitable match.

Once you’ve tackled paragraph headings, the next challenge is filling in missing details. Summary Completion questions require close attention to keywords and context, skills crucial for increasing your IELTS reading band score. Let’s take a closer look.

Summary Completion in The Water Crisis: Q8-13 Guide

Summary Completion questions test your ability to pick out precise details and vocabulary from the passage, often using paraphrased language that can be tricky to spot. In The Water Crisis, this means carefully matching the summary’s gaps with information that may be reworded or implied rather than stated directly.

Below are sample Summary Completion questions based on the water crisis reading answers passage to help you understand how this task appears in the IELTS test format.

Q8: Irrigation practices today waste a lot of water because they are not very efficient.

Focus: Identifying the inefficiency in how most irrigation systems operate

Strategy: Locate the paragraph discussing water use in agriculture and irrigation efficiency

Impact: Checks understanding of agricultural water usage and its shortcomings

Answer: inefficient Explanation: In Paragraph 2, it states that about 70% of fresh water goes to agriculture and adds that "current irrigation efficiency is estimated at only 50%." That means half the water used in irrigation is wasted. It also says that simple upgrades can improve this, but they’re lacking in poorer regions. This clearly shows that inefficient practices lead to major water loss, so the correct word is inefficient.

Q9: Many poor nations lack the ___________ and ____________ to modernise their irrigation systems.

Focus: Understanding what prevents developing countries from improving their irrigation systems

Strategy: Look for barriers mentioned in connection to irrigation upgrades

Impact: Tests your ability to extract paired factors limiting progress

Answer: investment, training Explanation: Again in Paragraph 2, it explains that "many developing countries lack the investment and training to implement such changes." This refers to modernising their inefficient irrigation systems. Both terms are clearly given and show why these nations can't adopt better technology. The blank asks for exactly what’s missing, so investment and training fit perfectly.

Q10: Compared to agriculture, industry produces much more __________ per litre of water used.

Focus: Comparing how efficiently water is used across sectors

Strategy: Spot the comparison between agriculture and industry in water productivity

Impact: Checks understanding of economic return from water use

Answer: output Explanation: Paragraph 2 mentions that industry "generates much more economic output per litre, around sixty times more than agriculture." This is a direct comparison. It highlights how industry gets significantly more value out of each litre of water. The word output is used in the same sentence and fits the context of productivity, making it the best answer here.

Q11: In the U.S., industries have managed to reduce their water usage by over 30% even though __________ has increased sharply.

Focus: Identifying a contrast between industrial output and water usage

Strategy: Look for figures showing what went up as water use went down

Impact: Tests comprehension of contrasts and efficiency improvements

Answer: output Explanation: Paragraph 3 says, “Since 1950, U.S. industrial output has quadrupled while water use has dropped by over 30%.” That means output (or production) increased sharply even though water usage went down. The word output connects directly with the rise in performance and matches the sentence’s contrast. It shows improved efficiency and fits the blank exactly.

Q12: Some governments, especially in __________ nations, continue to provide water at extremely low prices.

Focus: Identifying who still provides cheap water access

Strategy: Look for specific examples of low-cost or subsidised water

Impact: Measures your ability to extract country groupings and specific references

Answer: developing Explanation: In Paragraph 4, the passage clearly states, "In many lower-income countries, irrigation water is almost free." It also says that governments still offer water at very low prices, especially for agriculture. This directly ties the idea of underpriced water to developing nations, which are also called lower-income in the text. So developing is the correct answer.

Q13: Recycled water can now be used for purposes like farming and even in __________.

Focus: Understanding new uses for recycled water

Strategy: Identify specific uses mentioned for treated water

Impact: Tests your ability to connect water treatment with real-world applications

Answer: homes Explanation: Paragraph 5 explains how reused water is now treated and put to use. It mentions that “after appropriate treatment, it can be reused for farming or even reintroduced into domestic supply systems.” Then it adds, “In St. Petersburg, Florida, all municipal water is treated and reused in homes.” This confirms that homes are one of the new applications for recycled water. It fits logically and grammatically.
